Questions to ask?

With four months of electioneering ahead we can expect housing to be featured. All the main parties are in favour of more housing.
Now we know the arguments against, so anyone who bumps into a candidate or wishes to contact a candidate should ask some questions. For example:-

Why are we building so many houses which are unaffordable;

Could they explain why the Home Choice Register, which is fundamentally flawed, is being mis-used to support developments;

Do they seriously think that Cornwall (UK) can just go on with more and more development?
